I wonder why they were never able to replicate the same level of "virtualization" they managed with Windows 3.11 / Dos while running win9x-based OSes - like mounting a folder as the root drive or a cd rom drive. I guess at that point it would become simply a clone of the wine environment while using the original os binaries instead?
- fredoralive 1y agoDOS box basically provides its own BIOS and DOS, so int 21h and friends are implemented by the emulator, so it can do things like redirecting access to the real file system. Windows 9x doesn’t (normally) use real mode DOS / BIOS calls for disk access, it has its own 32 bit disk drivers and file systems running in the virtual machine manager kernel (vfat.vxd and so on). So DOSbox has to do things in a far more traditional way, presenting a virtual hard disc device etc.
